<p>The detector (100) of absolute pressure ratios comprises a box (110), a longitudinally movable interface member (120) which is linked at one of its ends to a bellows (130) which is linked, moreover, to the box, the bellows being subjected to a first pressure. The mobile interface member is linked, at its other end, to a membrane (140) linked, moreover, to the box, said membrane being subjected to a second pressure. The interface member (120) and the bellows (130) are surrounded by a vacuum delimited by a space (150) defined by the box (110), the interface member (120), the bellows (130) and the membrane (140).</p> |
